WILLIAM J. STILLING, OF ELlVII-IURST, NEW YORK, ASSIGNOR TO HECLA IRON WORKS, 015 BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

DOOR-HANGER.

LISSJIO.

Application filed December 2, 1915.

To all whom it may concern:

Be it known that I, WILLIAM J. STILLING, a citizen of the United States, and a resident of Elmhurst, in the county of Queens and State of New York, have invented certain new and useful Improvements in Door- Hangers, of which the following is a specification.

My invention relates to door hangers for supporting vertical sliding doors.

The object of the invention is the production of a ball-bearing door hanger in which the thrust on the ball-bearings is on the upper part of the ball containers whereby the weight of the door is transmitted vertically downward to the main supporting roller instead of outward as in previous ball-bearing hangers and thereby obviating the possibility and consequent danger of a distortion or injury to the frame of the hanger or to the bearings.

A further object of the invention is the production of a door hanger of the character above described in which the ball containers are held to the walls of the hanger by internal annular flanges only so that the necessity is obviated of using bolts and nuts or other cumbersome means for holding the ball containers and roller in position.

Other and further objects of the invention will appear from the following description forming a part of the specification, the invention consisting in the novel features and parts and combinations of the same hereinafter more particularly described and then specified in the claim.

In the accompanying drawing in which similar characters of reference indicate corresponding parts in both the views: Figure 1 indicates a side elevation (partly broken away) of my novel door hanger and Fig. 2 is a vertical cross-section taken on the line 22 Fig. 1.

Referring more particularly to both figures of the drawing: 1 indicates a Specification of Letters Patent.

suitable supporting track 5 spanning and fastened in any desirable manner to a door way and having a groove in its upper surface in which the roller 5 travels. The roller 5 is provided at either end thereof with a reduced and substantially horizontal hub portion 6 supported by a plurality of antifriction balls 7 forming bearings for the roller and retained in the caps or containers 3.

8 indicates a U-shaped piece to whose base a sliding door 9 is fastened preferably by the screws 10 as illustrated, although any other suitable fastening means may be employed if so desired. The U-shaped piece 8 is held or fastened to the door hanger preferably by the pins 11 passing through the walls of the hanger and the U-shaped piece as is clearly shown in Fig. 2. The pins 11 also serve as supports or bearings for the supplen'ientary rollers 12. If an obstruction in the path of the door is met during its movement or travel, an end of the door is very apt to tip up or rise. In such a contingency, as is obvious, either or both of the supplementary rollers contact with the under side of the track 5 forcing the door back into normal position without materially impeding the progress thereof as the contact between the track and the supp1ementary rollers is a rolling one.

It is manifest from the foregoing description of my improved door hanger that because of its novel construction the thrust on the ball-bearings due to the weight of the door is on the upper part of the caps or containers 3 and is a vertical one only, this being an important feature of the invention. Because of this feature the value of the hanger is greatly enhanced as the strain on the hanger is equally distributed throughout both its walls and the walls are not apt to become distorted or displaced from their normal positions as would be the case if a sidewise thrust were exerted against the main roller 5. A sidewise outward thrust against the ball-bearings would tend to distort or displace the walls and cause them to spread and would not only weaken the hanger but would interfere with the proper operation of the ball-bearings in their respective ball-races.

What I claim as my invention is In a door-hanger, the combination of a frame having parallel side walls from the lower ends of which a door is suspended, a I plurality of anti-friction balls, ba1l-retain- 111g caps held to thewalls of the frame by internal annular flanges and providing balllarged solid body portion with convex surfaces adapted to travel in a groove of a suitable track and having reduced and substantially horizontal integral hub portions supporting said anti-friction balls in their ball-races so that a vertical thrust is exerted against the ball-retaining caps by the antifriction balls due to the weight of the door. Signed at New York in the county of New York and State of New York this 29th day of November A. D. 1915.
